It's a PCH chip with a short marking SR40B (means FH82HM370).
You can search for this chip under the short marking "SR40B".

If the PCB is not in too bad condition it makes sense to check the resistances to ground on all power rails and replace the chip if everything is normal.
Note that there's a strong black glue under the chip. It's also need to clear the BIOS ME-region after replacing this chip.
